| I IIIIIIIII izeaiare fevv v THEODORE PETERS, ,or FERDINAND, NDIANA, Assreivon To THE PET-son PUMP COMPANY, orrDnDrNAND, INDIANA, A CORPORATION or INDIANA.

To all whom it may concern:

Be it known that I, THEODORE PETERs, a citizen of the United States, residing at Ferdinand, Indiana, have invented a certain new and useful Improvement in Air-Pumps for Water-Distributing Systems, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to'which it appertains to make and use the same. i

. This invention relates to water distribut- J ingsystems of the type that comprise a water container or reservoir submerged in a well or other body of water, and an air. pump for creating pressure in said container, so as to cause the water in same to flow through a distributing pipe that leads to the placewhere water is .to be consumed or used.

The mainobject of iny pne'sentjinventionis to provide a water distributing system 'of the general type referred to that comwhich is.

prises a manually-operated pump so constructed that the pressure in .the subinexpensive air pump for the purpose demerged water container will be relievediau tomatically when the operator releases the actuating device of the air pump, thereby permittmg the water container to automatically fill with water. j so Another object is to provide a pump or water distributing system of the character r'eferredto that can be installed easily and also adjusted easily, so as to vary the leverage of the actuating device.

And still another object is to provide an scribed which is of suchsimple-design that it is not apt to get out of order. -Other ob-- ects and desirable features of my invent1on will be hereinafter pointed out.

Figure 1 of the drawings is an elevational view, illustrating a water distributing system provided with an air pump constructed in accordance with my invention.

Fig. 2 is atop plan view of said air pump;

Fig.3 is a vertical sectional view, taken on the line 3-3 of Fig. 1.

that is submerged in a well a: or other body of water.

controlling device. The water container A 1 is provided at its lower end with an in wardly opening'check valve 1 that controls a port through which the water enters'the container A,'and the distributing pipe 0 is provided with a check valve 2 arranged in such a. manner that'it prevents the water in the distributing'pipe from flowirr'g' back wardly into the container A. 1 When the pump is operated pressure is created in they container A, thereby causing the water to y be forced out .of said container through the distributing pipe 0 to the point where the water is to be used.

-' In order that the container A will automatically fill with water, I have constructed thepump B in such a mann r that when the operator releases the actuati g device of said pump (pressure in the container A will be relieve thereby permitting the check valve 1 to open, and thus cause the waterfrom the v source of supply to flow into the container A In the form of myinventionherein shown the actuating device of thepump B consistsof. a hand-lever D that is pivotally connected to the piston E of the pump, one end of said lever being pivotally connected to a rockable fulcrum member 3. The cylinder 4 of the pum is provided at its lower end with-.a latera 1y projecting pipe 5 of said valve casing being connected by means of a pipe 5 with the interior'of the water container A. Check valves 6 and? are arranged in the valve casing F in such a manner that when the. piston E of the pump movesupwardly the valve 7 will seat and the valve 6 will open-and permit air to pass through a port 6 insaid valve casand thence through the pipe 5 into the cylinder 4 of the pump. On the downward stroke of the piston E the air which entered the cylinder of the ump on the upward strokeof the'piston wil .be comthrough the pipe 5 into the pipe 5 that leads .that leadsto a valve casing F, the interior automatically on the downward stroke of the piston E. The lever or actuating device D of the pump is provided with an air duct or passageway 8, shown in Fig. 4, which is connected by means of a flexible conduit 9 with the valve casing F of the pump, said air duct 8 being provided with a discharge port 8 that is controlled by a valve 10, shown in Fig. 5. When the valve 10 is open the submerged water container is in direct communication with the atmosphere through the pipe 5, the flexible conduit 9 and the air duct or passageway 8 in the pump actuating device D, the conduit 9 being connected to the valve casing F at a point between the discharge valve 7 and the air pipe 5 that leads to the water container A, as shown more clearly in Fig. 3 of the drawings. It is immaterial, so far as my broad idea is concerned,

what type of air' valve 10 is used for con-' trolling the air discharge port 8 but I prefer to combine the valve 10 with a hand grip 11 on the actuating lever D in such a manner that when the operator releases said hand grip, the valve 10 will open automatically, and thus permit the air to escape from the water container A. As shown in Figs. 1 and 5, the hand grip 11 is provided with a pivotally mounted portion 11*, preferably arranged on the underside of same, and the valve 10 is arranged on said pivotally mounted portion in such a manner that it will close the port 8 when the hand of the operator grasps the portion 11 of the hand grip and forces it upwardly. The valve 10 is normally held unseated by means of a spring 12 that exerts pressure on the movable portion 11 of the hand grip in a direction tending to force it away from the stationary portion of said hand grip.

The cylinder of the pump and the rockable fulcrum member 3 are carried by a bracket G that can be easily connected to a wall or other supporting structure, and in order that the pump may be adjusted so as to vary the leverage of the actuating device D, I have mounted the cylinder of the pump .on

. the supporting bracket G in such a manner that passes downwardly through an elon-- that said cylinder can be moved toward or away from the-rockable fulcrum member 3. As shownin Fig. 3 of the drawings, the cylinder of the pump is provided at its lower end with a non-circular-shaped projection 13 gated slot 14 on the supporting bracket G,

said projection having a threaded portion 13? on which a nut 15 is mounted so as to securely clamp the cylinder to the supporting bracket. The piston rod 16 ofthe pump is pivotal-ly-connected at'its upper end to a sleeve 17 that is adjustably mounted on the pump actuating lever D, said sleeve being old in operative position on said lever by frictional engement with same, or in any other desired manner. By loosening the justed in such a manner that it can be easily operated by a child.

The particular details of construction of the pump-are of course immaterial so far as my broad idea is concerned, 'but in order that the pump can be manufactured and sold at a low cost, and in order that it will successfully withstand rough, continuous usage, I prefer to form the actuating device D of the pump from a piece of ordinary metal pipe whose end is secured to a casting 18 provided with integral cars 19 that embrace the fulcrum member 3 and which are secured to said member by means of a pivot 20. The fulcrum member 3 is also preferably formed from a piece of pipe whose lower end is connected to a casting 21 that is pivotally connected by a pin 22 to integral lugs or ears 23 on the bracket G. The hand grip 11 also preferably consists of a hollow casting into which one end of the actuating device D is threaded. The valve casing F can be formed conveniently from a casting of simple I claim, and desire to secure by Letters Patent, is:
